Looking to upgrade the front brakes on my 05sti to AP 6pots( either full AP or Godspeed/AP ) but I'm a bit worried about the lack of pad options. Does anyone have these calipers with any other pads apart from DS2500/3000, such as PF01/03 or Pagid.
I've had problems using DS2500's on track before( not on the scooby) and i don't want to shell out £1400 to be stuck with a pad I'm not completely happy with.
Demon Tweeks had some other options but its a deeper pad and would need machining, i asked Ian for alternative pad options but he didn't reply.
Will the Ferodo pads will work better in the AP's, I've only used them on standard brakes before, is everybody happy with the DS2500/AP combo for full on trackdays?

 

If you look at the 330mm 5570 caliper instead of the 355mm kit your pad option choice is huge. I'm using Pagid RS29 with PF aftermarket discs in my 5570 calipers and they are a delight to use and I don't feel any need for anything bigger. Alyn at ASPerformance can supply 0191 4103770.

If you're going on track then remove your false fog light covers and cut a 3" square hole in the soft plastic wheel arch liners so that more air can get behind the wheels and help with brake cooling, this cured brake overheating probs I had. Ideally ducting to the disc inner would be best but is difficult to arrange. Also take off the splash guards when you change the brakes.

 

Hi Tinhead
Sorry didn't get an email from you otherwise you would have had a reply , In my opinion the 7040 caliper is a better caliper as it has far better dust sealing , I have had loads of the older style AP calipers in to recondition as the pistons get pitted from being out in the open , they pick up stone chips then corrode , so when they need rebuilding usually all of the pistons need changing , and they are close on £30 each , the 7040 calipers have outer boots over the pistons that fully protects them , I have yet to see a 7040 caliper with damaged pistons , they are far more reliable for road use .

All of the pad manufacturers supply pads for the 7040 calipers , the pagid number is ES20346

Hope this helps
Cheers Ian

 

Regarding the deeper pad , the discs I make use the larger wider pad , so you dont have to get the cut down pads as in some of the full AP kits
Cheers Ian

 

Thanks for the replies guys.
D1CCY, i have thought about cutting holes in the arch liner before but without ducting i wasn't sure it would be effective but if you found it helps then I'll give it a go.
When you say splash guard do you mean the cover that fits behind the disc?
Ian, if your disks allow me to use the D61 deeper pad then that opens up the pad options( at least Pagid anyway).
I'll ring you next week with the order.

 

PF do a 97 compound for that caliper too.

Running the more expensive CP5570 calipers here and they did require an overhaul before I fitted them (purchased used), so I can see where Ian is coming from regarding the better seals on the CP7040.

Have a chat with AP - they are always very informative and helpful: 024 76639595

AP have 10% off at the moment on their genuine kits

 

ian supplied me with my 7040's some 5 years ago now. I have always used the ds2500's and done the ring 3 times plus numerous track days without a problem.. definatly going to retain them for racing my bugeye next year
